President Trump plans to increase funding for the military by $54 billion while slicing the same amount from domestic programs and foreign aid, the White House said on Monday.

Trump administration officials briefed reporters on the budget but didn’t offer specific details of where the reductions would take place, saying the majority of “lower priority programs and most federal agencies” will see cuts.

The $54 billion increase – a 10 percent increase for the Pentagon – would fulfill a Trump campaign pledge to bolster the military, the White House said.

Speaking to a gathering of the nation’s governors on Monday during a White House ceremony, Trump said the budget would concentrate on public safety and national security.

“It will include a historic increase in defense spending to rebuild the depleted military of the US at a time we most need it,” he said.

Trump said the increase in military spending is a ” landmark event, a message to the world in these dangerous times of american strength, security, and resolve.”

“We must ensure that our courageous servicemen and women have the tools they can be to deter war, and when called upon to fight in our name, only do one thing – win. we have to win. We have to start winning wars again,” he said.

The administration will begin notifying federal agencies later Monday of the new president’s first federal budget, revealing Trump’s priorities in terms of dollars and cents.

Trump is expected to reveal details Tuesday night in a televised speech to a joint session of Congress on Capitol Hill, the first of its kind since he was sworn in last month.

The speech will not only focus on the budget. Trump is expected to deliver more details on his plan to repeal and replace ObamaCare and on his plan to reform the complex tax code.

His budget is expected to include steep cuts to the Environmental Protection Agency but he will leave spending on Social Security and Medicare, the two biggest entitlement programs, unchanged.

“We are not touching those now. So don’t expect to see that as part of this budget,” Steven Mnuchin told “Fox News Sunday.”
